Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, specifically to an adhesive application device. Background Technology

[0002] In related technologies, battery tabs require adhesive application on the production line during battery assembly. This is achieved by drawing adhesive tape from a reel onto the surface of the tab placed on a tab positioning fixture and applying pressure. Some production lines simply use conveyor belts to transport the tabs to their corresponding workstations for adhesive application. Applying adhesive to multiple tabs often requires multiple independent production lines operating within the workshop, resulting in large space requirements and numerous pieces of equipment, thus increasing workshop operating costs. Utility Model Content

[0003] The embodiments of this application provide an adhesive application device that can improve the technical problem of large space occupation in production lines.

[0004] An embodiment of this application provides an adhesive applicator for applying adhesive to electrode tabs, comprising:

[0005] Mounting substrate;

[0006] A positioning fixture, connected to the mounting base, is provided with an assembly part for positioning and mounting the electrode tab;

[0007] Multiple winding elements are movably connected to the mounting base for winding tape;

[0008] The positioning fixture is provided with a plurality of assembly parts; a plurality of winding parts are disposed on opposite sides of the mounting base along a first direction, and at least two assembly parts are disposed at different positions on the positioning fixture along the first direction, so that the plurality of winding parts are adapted to provide tape to the different assembly parts respectively.

[0009] By integrating multiple rolls of tape onto opposite sides of a mounting base, which serves as a common mounting reference for the multiple rolls of tape, the tape application equipment can deliver different rolls of tape to different assembly sections in a timed or simultaneous manner. This enables the application of tape to multiple electrodes on a single device, improving the spatial integration of the tape application equipment.

[0010] In one embodiment, the plurality of the windings include:

[0011] The first winding is rotatably connected to the mounting base about the first rotation axis;

[0012] The second winding is rotatably connected to the mounting base about the second rotation axis;

[0013] The first winding member and the second winding member are disposed on opposite sides of the positioning fixture along the first direction; the first rotation axis and the second rotation axis are spaced apart in a second direction perpendicular to the first direction, so that the first winding member and the second winding member are rotatably connected to different positions of the mounting base.

[0014] By adopting the above scheme, the specific assembly positions of the first winding and the second winding on the mounting base are staggered, and the first winding and the second winding can work relatively independently, which is conducive to the integrated installation of the first winding and the second winding on the mounting base and the spatial layout is reasonable.

[0015] In one embodiment, the first rotation axis and the second rotation axis are arranged in parallel.

[0016] This setup allows multiple tapes to be drawn out from the first and second windings in roughly the same direction, facilitating the centralized configuration of other tape-handling components on the mounting base and further improving the rationality of the spatial layout to reduce the spatial integration of the tape-applying equipment.

[0017] In one embodiment, the assembly part is configured as an assembly groove provided in the positioning fixture, the assembly groove being used for inserting the electrode tab; the assembly groove extends through the positioning fixture along the second direction to expose the opposing surfaces of the electrode tab embedded in the assembly groove along the second direction;

[0018] At least two of the winding members are provided on one side of the mounting base along the first direction, such that the at least two winding members are adapted to provide tape to the two opposite surfaces of the tabs embedded in the mounting groove.

[0019] Using the above method, different winding parts located on the same side of the mounting base can respectively provide tape to the two opposite surfaces of the same electrode, which makes it easier to apply tape to both surfaces of the electrode at one time in the future, further improving production efficiency.

[0020] In one embodiment, the adhesive applicator further includes:

[0021] A clamping assembly, movably connected to the mounting base and located between the positioning fixture and the winding member, is adapted to clamp and move the tape extended from the winding member;

[0022] A cutting assembly, movably connected to the mounting base and located between the clamping assembly and the winding member, is adapted to cut the tape located between the winding member and the clamping assembly by movement of the cutting assembly;

[0023] A transfer assembly, movably connected to the mounting base and located between the cutting assembly and the clamping assembly, is adapted to transfer the tape cut by the cutting assembly to the assembly slot by its own movement.

[0024] In practical applications, the tape can be held by the clamping component, and then the cutting component can cut the tape to cut off a portion of the tape from another portion of the tape wound on the winding component. Then, the transfer component can transport the tape to the assembly slot to realize the cutting and transfer of the tape.

[0025] In one embodiment, the adhesive applicator further includes:

[0026] An adapter block is disposed on the side of the cutting assembly away from the clamping assembly, and the adapter block has adapter grooves on opposite sides along the second direction for the tape to pass through.

[0027] Wherein, at least two of the cutting components are respectively disposed on opposite sides of the adapter block along the second direction; the cutting components include:

[0028] A cutting tool is movably connected to the mounting base to have a cutting position relative to the mounting base suitable for cutting the tape located between the clamping assembly and the adapter block, and a clearance position suitable for avoiding the tape located between the clamping assembly and the adapter block.

[0029] A first driving member, connected to the cutting tool, is used to drive the cutting tool to move between the cutting position and the avoidance position.

[0030] This setup uses an adapter slot to limit the tape's position, ensuring that the cut tape has a relatively fixed shape when cut with a cutting tool, thus preventing abnormal overlap of the tape and ensuring a good subsequent application effect.

[0031] In one embodiment, the cutting component further includes:

[0032] A locking member is movably connected to the mounting base and faces the adapter groove in the second direction, such that the locking member has a locking position relative to the mounting base suitable for contacting the tape at the adapter groove, and an unlocking position suitable for disengaging from the tape at the adapter groove.

[0033] The second driving component, connected to the locking component, is used to drive the locking component to move between the locked position and the unlocked position.

[0034] Based on the adapter block, a locking component can be added to fix the tape during cutting, preventing the tape from loosening and ensuring smooth cutting, while also making the length variation of the cut tape relatively small.

[0035] In one embodiment, the clamping assembly includes:

[0036] A pneumatic gripper is movably connected to the mounting base and located on the side of the cutting tool away from the adapter block, so as to have at least a gripping position suitable for close to the adapter block and a fixed distance position away from the adapter block relative to the mounting base;

[0037] The third driving component is connected to the pneumatic gripper and is used to drive the pneumatic gripper to move between the gripping position and the fixed distance position.

[0038] Using the above method, a pneumatic gripper can be used to hold the tape exposed in the fitting groove. Then, the third drive unit drives the pneumatic gripper to move, so that the tape is pulled. When the tape is cut off by the cutting tool, a specific length of tape can be cut according to the displacement of the tape pulled by the pneumatic gripper, so as to ensure that the tape length is adapted to the size of the electrode.

[0039] In one embodiment, at least two of the transfer components are respectively disposed on opposite sides of the adapter block along the second direction; the transfer components include:

[0040] A negative pressure adsorption element is movably connected to the mounting base to have an adsorption position relative to the mounting base suitable for proximity to the tape located between the cutting assembly and the clamping assembly, and a transfer position suitable for distance from the tape located between the cutting assembly and the clamping assembly.

[0041] A fourth driving member is connected to the negative pressure adsorption member to drive the negative pressure adsorption member to move between the adsorption position and the transfer position. The fourth driving member is movably connected to the mounting base to be adapted to move the negative pressure adsorption member between the adapter block and the positioning fixture when moving relative to the mounting base.

[0042] The fifth driving member is connected to the fourth driving member to drive the fourth driving member to move closer to or away from the positioning fixture, and to move the negative pressure adsorption member between the adapter block and the positioning fixture.

[0043] Using the above scheme, the two separate transfer components can each utilize a negative pressure suction element to provide negative pressure and suck up the cut tape. Then, driven by the fourth and fifth driving elements, the negative pressure suction element moves the tape to the positioning fixture for bonding with the electrode, thus achieving tape transfer. The negative pressure suction method has minimal impact on the shape of the tape, ensuring its flatness and guaranteeing effective electrode bonding.

[0044] In one embodiment, the adhesive applicator further includes:

[0045] Multiple tension rollers are connected to the mounting base and located between the adapter block and the winding member to guide the tape from the winding member to the adapter block;

[0046] A sixth driving member is connected between the mounting base and at least one of the tensioning wheels to be adapted to drive at least one of the tensioning wheels to move relative to the mounting base.

[0047] Multiple tensioning rollers adjust the direction of the tape's extension, while the sixth drive unit straightens the tape by driving the tensioning rollers, ensuring stable subsequent cutting, transfer, and application.

[0048] In one embodiment, the adhesive applicator further includes:

[0049] A damper, fixed to the mounting base, is used to provide an assembly for the winding to adjust the speed at which the winding moves relative to the mounting base;

[0050] This setup allows the damper to provide a force that resists the movement of the winding component when it is pulled before the tape is cut and moved relative to the mounting base. This can be used to adjust the speed at which the tape is pulled, and also to further ensure that the tape remains taut when it is pulled.

[0051] The beneficial effects of the embodiments of this application are as follows:

[0052] In the embodiments of this application, by integrating multiple winding components on opposite sides of a mounting base, with the mounting base serving as a common mounting reference for multiple rolls of tape, the adhesive applicator can deliver different tapes to different assembly sections in a time-sharing or simultaneous manner. This enables the application of adhesive to multiple electrodes on a single device. The identical mounting reference for multiple winding components facilitates electrode application in a smaller space, improving the spatial integration of the adhesive applicator and enabling simultaneous application of adhesive to multiple electrodes, thereby increasing production efficiency. This addresses the technical problems of low space utilization and limited production efficiency in electrode application production lines. Attached Figure Description

[0078] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0079] Embodiments of this application provide an adhesive applicator 100, which can be used for at least adhesive application to tabs 200.

[0080] Reference Figures 1 to 7 As shown, the adhesive application equipment 100 includes: a mounting base 101, a winding component 102, a damper 103, a tensioning wheel 104, an adapter block 105, a clamping assembly 106, a cutting assembly 107, a transfer assembly 108, and a positioning fixture 109.

[0081] The mounting base 101 can be an integrated structure for mounting components such as the winding component 102, damper 103, tensioning wheel 104, adapter block 105, clamping assembly 106, cutting assembly 107, transfer assembly 108, and positioning fixture 109. The mounting base 101 can be a single, integral structure, or, as described above... Figure 1 and Figure 2 As shown, the mounting base 101 can be a combination of multiple components. In practical applications, the multiple components of the mounting base 101 can be fixed in a specific area of ​​the workshop, thereby using that specific area of ​​the workshop as a work station for electrode adhesive application.

[0082] Reference Figure 1 and Figure 3As shown, the positioning fixture 109 is connected to the mounting base 101 and has an assembly part 109a for positioning the mounting tab 200, so as to place the tab 200 to be glued in a specific area of ​​the glue application equipment 100. The positioning fixture 109 is fixed to the mounting base 101, for example. Alternatively, the positioning fixture 109 can be connected to components such as cylinders, electric telescopic rods, and hydraulic cylinders on the mounting base 101, and can move relative to the mounting base 101 to cooperate with other components in the workshop, so that the electrode can flow between these components and the glue application equipment 100.

[0083] Multiple winding elements 102 are movably connected to the mounting base 101. The winding elements 102 are used to wind the tape 300. During the application of the tape, the tape 300 on the winding elements 102 can be provided to the positioning fixture 109.

[0084] In a specific embodiment, the winding element 102 may be configured, for example, to rotate a roll of adhesive disposed on the mounting base 101.

[0085] It should be noted that, unless otherwise stated, the term "multiple" in this application refers to "two or more", which will not be repeated below.

[0086] The positioning fixture 109 is provided with multiple assembly parts 109a, which can position and place multiple electrode sheets on the positioning fixture 109 so that the multiple electrode sheets can be glued on the positioning fixture 109 respectively.

[0087] Multiple winding elements 102 are disposed on opposite sides of the mounting base 101 along a first direction to fully utilize the space on both sides of the mounting base 101 for placing the tape 300. At least two mounting portions 109a are disposed at different positions on the positioning fixture 109 along the first direction, so that the multiple winding elements 102 are adapted to supply tape 300 to different mounting portions 109a respectively, thereby allowing tape 300 to be supplied to the positioning fixture 109 using different winding elements 102, and electrode sheets to be applied at different mounting portions 109a respectively.

[0088] By adopting the above solution, by integrating multiple winding components 102 on opposite sides of the mounting base 101, and using the mounting base 101 as a common mounting reference for multiple rolls of tape 300, the tape application equipment 100 can transport different tapes 300 to different assembly sections 109a in a time-sharing or simultaneous manner. This enables the application of tape to multiple electrodes on a single device. The identical mounting reference of the multiple winding components 102 facilitates electrode application in a smaller space, improves the spatial integration of the tape application equipment 100, and allows for simultaneous application of tape to multiple electrodes, thereby increasing production efficiency. This addresses the technical problems of low space utilization and limited production efficiency in electrode application production lines.

[0089] As a specific solution, the multiple winding elements 102 disposed on both sides of the mounting base 101 include: a first winding element 102a and a second winding element 102b.

[0090] The first winding member 102a is rotatably connected to the mounting base 101 about a first rotation axis L1, and the second winding member 102b is rotatably connected to the mounting base 101 about a second rotation axis L2. The first winding member 102a and the second winding member 102b are disposed on opposite sides of the positioning fixture 109 along a first direction. Specifically, the first winding member 102a and the second winding member 102b can be two rolls of adhesive tape installed on both sides of the mounting base 101. The adhesive tape 300 can be wound on the first winding member 102a and the second winding member 102b. In use, the adhesive tape 300 is fed out from the first winding member 102a or the second winding member 102b by pulling the adhesive tape 300 to rotate the first winding member 102a or the second winding member 102b.

[0091] In some embodiments of this application, the first rotation axis L1 and the second rotation axis L2 are spaced apart in a second direction perpendicular to the first direction, so that the first winding member 102a and the second winding member 102b are rotatably connected to different positions on the mounting base 101. Considering the assembly of the first winding member 102a and the second winding member 102b on the mounting base 101, the staggered arrangement of the first rotation axis L1 and the second rotation axis L2 is beneficial for the rational arrangement of the spatial positions of each winding member 102. During assembly, the first winding member 102a and the second winding member 102b are staggered to avoid hindering each other's assembly. At the same time, it also makes the space occupied by the first winding member 102a and the second winding member 102b in the first direction less, which can reduce the space occupied by the adhesive applicator 100 in the first direction.

[0092] The above arrangement allows the first winding 102a and the second winding 102b to be staggered in their specific assembly positions on the mounting base 101, enabling the first winding 102a and the second winding 102b to work relatively independently. This facilitates the integrated installation of the first winding 102a and the second winding 102b on the mounting base 101, resulting in a reasonable spatial layout.

[0093] In the specific design, the first rotation axis L1 and the second rotation axis L2 are arranged in parallel. More specifically, the extending directions of the first rotation axis L1 and the second rotation axis L2 can be the same as the first direction. This arrangement allows multiple tapes 300 to be drawn out from the first winding member 102a and the second winding member 102b respectively along approximately the same direction. This facilitates the centralized configuration of other components used for processing the tapes 300 on the mounting base 101, further improving the rationality of the spatial layout and reducing the spatial integration of the adhesive application equipment 100.

[0094] As an example of a specific structure for positioning and mounting the tab 200 using the positioning fixture 109, the assembly part 109a is configured as an assembly groove 109b provided in the positioning fixture 109. The assembly groove 109b is used for embedding the tab 200. In a specific embodiment, the shape and size of the assembly groove 109b match the tab 200, so that the tab 200 can be positioned by the groove wall of the assembly groove 109b. More specifically, when applying adhesive to tabs 200 of different sizes, the positioning fixture 109 with different sizes of assembly grooves 109b can be replaced. Therefore, the positioning fixture 109 can be detachably fixed on the mounting base 101 using a threaded connection or other detachable fixing method, making it easy to replace the matching positioning fixture 109 according to the size of the tab 200.

[0095] The assembly groove 109b penetrates the positioning fixture 109 along the second direction to expose the opposite surfaces of the tab 200 embedded in the assembly groove 109b along the second direction. Specifically, the assembly groove 109b can be a stepped groove with at least two parts of different widths, so that the groove wall of the assembly groove 109b can support the tab 200, and the two opposite surfaces of the tab 200 along the second direction are exposed in the assembly groove 109b, and the tape 300 can be attached to these two surfaces.

[0096] Correspondingly, at least two winding members 102 are provided on one side of the mounting base 101 along the first direction, so that the at least two winding members 102 are adapted to provide adhesive tape 300 to the two opposite surfaces of the electrode tab 200 embedded in the assembly groove 109b respectively. With the above solution, different winding members 102 located on the same side of the mounting base 101 can provide adhesive tape 300 to the two opposite surfaces of the same electrode respectively, which facilitates the application of adhesive to the two surfaces of the electrode in one go in the subsequent process, further improving production efficiency.

[0097] The clamping assembly 106 of this application is movably connected to the mounting base 101 and located between the positioning fixture 109 and the winding member 102, adapted to clamp and move the tape 300 extending from the winding member 102. The clamping assembly 106 clamps and moves the tape 300, and the length of the subsequently cut tape 300 is controlled by the displacement of the clamping assembly 106. The cutting assembly 107 is movably connected to the mounting base 101 and located between the clamping assembly 106 and the winding member 102, adapted to cut the tape 300 located between the winding member 102 and the clamping assembly 106 by the movement of the cutting assembly 107, and the cut tape 300 can then be transported to the positioning fixture 109. The transfer assembly 108 is movably connected to the mounting base 101 and located between the cutting assembly 107 and the clamping assembly 106, adapted to transfer the tape 300 cut by the cutting assembly 107 to the assembly slot 109b by its own movement.

[0098] In practical applications, the clamping component 106 can be used to clamp the tape 300, and then the cutting component 107 can cut the tape 300 to cut off a portion of the tape 300 from another portion of the tape 300 wound on the winding component 102. Then, the transfer component 108 can be used to transport the tape 300 to the assembly slot 109b to realize the cutting and transfer of the tape 300.

[0099] Reference Figure 4 , Figure 5 and Figure 6 As shown, the adapter block 105 mentioned above is located on the side of the cutting assembly 107 away from the clamping assembly 106, and the adapter block 105 has adapter grooves 105a on both opposite sides along the second direction for the tape 300 to pass through. Figures 1 to 7 In the specific embodiment of the example, the first direction is shown as the front-to-back direction in the figure, and the second direction is shown as the up-and-down direction. Two adapter grooves 105a are formed on the upper and lower sides of the adapter block 105, respectively, and the adapter grooves 105a penetrate the adapter block 105 along the left-to-right direction as shown in the figure, allowing the tape 300 to extend in the left-to-right direction at the adapter grooves 105a. More specifically, the adapter block 105 can be stably secured to the adapter block 105 by creating a negative pressure channel communicating with the adapter grooves 105a, preventing the tape 300 located at the adapter groove 105a on the lower side of the adapter block 105 from detaching from the adapter block 105. Alternatively, other parts of the adapter block 105 or other components on the adapter block 105 can be used to support the tape 300, allowing the tape 300 to stably pass through the adapter grooves 105a.

[0100] It is understandable that, based on the arrangement of multiple assembly slots 109b, the adapter block 105 may have multiple adapter slots 105a at the same end along the second direction, so as to guide multiple tapes 300 through the adapter slots 105a, which facilitates the application of adhesive to multiple tabs 200.

[0101] In some embodiments, at least two cutting components 107 are respectively disposed on opposite sides of the adapter block 105 along the second direction, so as to cut the tape 300 passing through different adapter grooves 105a respectively, thereby cutting off at least two sections of tape 300 for subsequent application of adhesive to at least two tabs 200.

[0102] The cutting assembly 107 includes: a cutting blade 107a, a first drive member 107b, a locking member 107c, and a second drive member 107d.

[0103] The cutting blade 107a is movably connected to the mounting base 101 to have a cutting position relative to the mounting base 101 suitable for cutting the tape 300 located between the clamping assembly 106 and the adapter block 105, and a clearance position suitable for avoiding the tape 300 located between the clamping assembly 106 and the adapter block 105. A first drive member 107b is connected to the cutting blade 107a for driving the cutting blade 107a to move between the cutting position and the clearance position.

[0104] In the specific embodiment shown in the figure, the first driving component 107b drives the cutting blade 107a to slide vertically. The cutting blade 107a moves from the avoidance position to the cutting position, and the tape 300 held by the clamping component 106 is cut off by the cutting blade 107a. Due to the limiting effect of the adapter groove 105a on the tape 300, the tape 300 does not move around during the cutting process. This setting uses the adapter groove 105a to limit the tape 300, and when the cutting blade 107a cuts the tape 300, the shape of the cut tape 300 is relatively fixed, avoiding abnormal overlap of the tape 300 and resulting in poor subsequent adhesive application.

[0105] The locking member 107c is movably connected to the mounting base 101 and faces the adapter groove 105a in the second direction, so that the locking member 107c has a locking position relative to the mounting base 101 suitable for contacting the tape 300 at the adapter groove 105a, and an unlocking position suitable for disengaging the tape 300 at the adapter groove 105a; the second driving member 107d is connected to the locking member 107c and is used to drive the locking member 107c to move between the locking position and the unlocking position. Based on the adapter block 105, the locking member 107c is further configured to fix the tape 300 when cutting the tape 300, to prevent the tape 300 from loosening and to ensure smooth cutting, while making the length variation of the cut tape 300 relatively small.

[0106] exist Figure 1 and Figure 4 In the specific embodiment of the example, the locking element 107c is an integral unit consisting of a connecting block 110 connected to the second driving element 107d and a rubber pad (not shown in the figure) provided on the connecting block 110, wherein the rubber pad is located on the side of the connecting block 110 closer to the adapter block 105. The second driving element 107d drives the locking element 107c to move up and down, and the rubber pad can contact the tape 300 at the adapter block 105 at the locked position to apply pressure to the tape 300. When the cutting tool 107a cuts the tape 300, one end of the tape 300 is fixed by the locking element 107c, which is beneficial for cutting a specific length of tape 300.

[0107] The clamping assembly 106 includes a pneumatic gripper 106a and a third drive member 106b.

[0108] The pneumatic gripper 106a is movably connected to the mounting base 101 and is located on the side of the cutting tool 107a away from the adapter block 105, so that it has at least a gripping position close to the adapter block 105 and a fixed distance position away from the adapter block 105 relative to the mounting base 101; the third drive member 106b is connected to the pneumatic gripper 106a and is used to drive the pneumatic gripper 106a to move between the gripping position and the fixed distance position.

[0109] exist Figure 1 and Figure 4 In the specific embodiment of the example, the third drive unit 106b drives the pneumatic gripper 106a to move in the left-right direction as shown in the figure. When the pneumatic gripper 106a moves to the leftmost end of its stroke, it is in the gripping position. The pneumatic gripper 106a works to grip the end of the tape 300. Then, the third drive unit 106b drives the pneumatic gripper 106a to move to the right until the tape 300 between the adapter block 105 and the pneumatic gripper 106a has a specific length. The cutting component 107 then cuts the tape 300 to a fixed length, thus achieving fixed-length cutting of the tape 300.

[0110] Using the above solution, the pneumatic gripper 106a can be used to hold the tape 300 exposed in the fitting groove 105a. Then, the third drive unit 106b drives the pneumatic gripper 106a to move, so that the tape 300 is pulled. When the cutting tool 107a cuts the tape 300, according to the displacement of the tape 300 pulled by the pneumatic gripper 106a, a specific length of tape 300 can be cut to ensure that the length of the tape 300 is adapted to the size of the electrode sheet.

[0111] The cut tape 300 can be conveyed to the positioning fixture 109 using the transfer assembly 108. In one embodiment, at least two transfer assemblies 108 are respectively disposed on opposite sides of the adapter block 105 along a second direction to respectively transport tape 300 suitable for mounting to the two opposite surfaces of the electrode sheet. See also Figure 2 , Figure 4 and Figure 5 As shown, the transfer assembly 108 includes: a negative pressure adsorption component 108a, a fourth driving component 108b, and a fifth driving component 108c.

[0112] The negative pressure adsorption component 108a is, for example, an air nozzle connected to equipment such as a negative pressure fan, which can adsorb the tape 300 by using the negative pressure at the air nozzle. The negative pressure adsorption component 108a is movably connected to the mounting base 101 so as to have an adsorption position suitable for approaching the tape 300 located between the cutting assembly 107 and the clamping assembly 106, and a transfer position suitable for moving away from the tape 300 located between the cutting assembly 107 and the clamping assembly 106.

[0113] The fourth driving member 108b is connected to the negative pressure adsorption member 108a to drive the negative pressure adsorption member 108a to move between the adsorption position and the transfer position. The fourth driving member 108b is movably connected to the mounting base 101 to be adapted to drive the negative pressure adsorption member 108a to move between the adapter block 105 and the positioning fixture 109 when moving relative to the mounting base 101.

[0114] The fifth drive member 108c is connected to the fourth drive member 108b to drive the fourth drive member 108b to move closer to or further away from the positioning fixture 109, and to drive the negative pressure adsorption member 108a to move between the adapter block 105 and the positioning fixture 109.

[0115] Reference Figure 5 As shown, the fourth driving member 108b drives the negative pressure adsorption member 108a to move in the up and down direction, and the fifth driving member 108c drives the fourth driving member 108b and the negative pressure adsorption member 108a to move left and right as a whole. After the negative pressure adsorption member 108a moves and adsorbs the cut tape 300, the fourth driving member 108b drives the negative pressure adsorption member 108a to move up and down to reset. Then, the fifth driving member 108c drives the negative pressure adsorption member 108a to move to the right, and the fourth driving member 108b drives the negative pressure adsorption member 108a to move down again to transfer the tape 300 to the electrode surface placed at the positioning fixture 109.

[0116] Using the above scheme, the two different transfer components 108 can respectively use the negative pressure adsorption component 108a to provide negative pressure to pick up the cut tape 300. Then, driven by the fourth drive component 108b and the fifth drive component 108c, the negative pressure adsorption component 108a drives the tape 300 to the positioning fixture 109 to combine with the electrode, thus realizing the transfer of the tape 300. The negative pressure adsorption method has little impact on the shape of the tape 300, ensuring the flatness of the tape 300 to ensure the adhesion effect of the electrode.

[0117] In the specific design, the first driving component 107b, the second driving component 107d, and the fourth driving component 108b are all fixed to an integrated component 111 connected to the fifth driving component 108c, so that the cutting blade 107a, the locking component 107c, and the negative pressure adsorption component 108a can be driven by the fifth driving component 108c to move synchronously. This allows these components to have the same mounting reference, ensuring that the length variation of each tape 300 cut multiple times is small.

[0118] In a more specific embodiment, after the adhesive tape 300 is transferred onto the positioning fixture 109, the locking member 107c is aligned with the electrode and adhesive tape 300 on the positioning fixture 109 by the driving of the fifth driving member 108c. Then, the movement of the locking member 107c can be used to press the electrode and adhesive tape 300 together, thus achieving adhesive bonding of the electrode. The adhesive tape 300 can also be tightly bonded to the electrode in other ways, and this application does not limit this method.

[0119] A plurality of the aforementioned tension rollers 104 are also linked to the mounting base 101. The tension rollers 104 are rotatably connected to the mounting base 101 and are located between the adapter block 105 and the winding member 102, adapted to guide the tape 300 from the winding member 102 to the adapter block 105. The adhesive applicator 100 also includes a sixth drive member 112 connected between the mounting base 101 and at least one tension roller 104, adapted to drive at least one tension roller 104 to move relative to the mounting base 101. As the tape 300 extends from the winding member 102 to the adapter block 105, it passes around each tension roller 104, using the tension rollers 104 to guide the extension direction of the tape 300. The sixth drive member 112, by moving the tension rollers 104, controls the force applied by the tension rollers 104 to the tape 300, straightening the tape 300 for subsequent cutting.

[0120] By adopting the above scheme, the extension direction of the tape 300 is adjusted by multiple tensioning rollers 104 on the one hand, and the sixth driving component 112 can drive the tensioning rollers 104 to straighten the tape 300, so as to ensure that subsequent cutting, transfer and application can be carried out stably.

[0121] In a more specific embodiment, the adhesive applicator 100 further includes: a weight pan 113, a lead wire 114, and weights 155. The weight pan 113 is movably connected to the mounting base, and the weights 155 are detachably mounted on the weight pan 113 to adjust the overall weight of the weight pan 113 and the weights 155. The lead wire 114 connects the weight pan 113 to at least one tensioning wheel 104. This arrangement allows for adjustment of the force exerted by the tensioning wheel 104 on the adhesive tape 300 by controlling the total weight of the weights 155 mounted on the weight pan 113, thereby ensuring stable delivery of the adhesive tape 300 to the adapter block 105.

[0122] The aforementioned damper 103 is fixed to the mounting base 101 and is used to provide components for the winding member 102 to adjust the speed at which the winding member 102 moves relative to the mounting base 101. The damper 103 can be a commercially available electromagnetic damper 103, hydraulic damper 103, etc., and this application does not impose any specific limitations on it.

[0123] The damper 103 is designed to provide a force that resists the movement of the winding member 102 when it is pulled before the tape 300 is cut and the winding member 102 moves relative to the mounting base 101. This can be used to adjust the speed at which the tape 300 is pulled, and also to further ensure that the tape 300 remains straight when it is pulled.

[0124] It should be noted that the first driving component 107b, the second driving component 107d, the third driving component 106b, the fourth driving component 108b, the fifth driving component 108c, the sixth driving component 112, etc. mentioned in this application can be cylinders, hydraulic cylinders, electric telescopic rods, etc., and this application does not limit them.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application.
